â  â  abstract â  â  the quran has been analyzed by many commentaries from many aspects including its rhetoric and style. it is questionable to grasp the arcane outstanding position of the quran in terms of its form, meaning, or rhetoric. of the rhetoric of the quran, oaths indicate miracle of the quran. oaths and their answers are in line with aggregates of all contexts as well as form and mea...

We developed a self-consistent screened-Korringa± Kohn± Rostoker (KKR) method in an ab initio tight-binding formulation. The reduction in numerical e€ ort in comparison with that required for the standard KKR method is achieved by the choice of a suitable reference system. Following the idea of Zeller et al. (1995, Phys. Rev. B, 52, 8807), reference systems with repulsive mu n-tin potentials o...

Lactococcus lactis â-phosphoglucomutase (â-PGM) catalyzes the interconversion of â-D-glucose 1-phosphate (â-G1P) and â-D-glucose 6-phosphate (G6P), forming â-D-glucose 1,6-(bis)phosphate (âG16P) as an intermediate. â-PGM conserves the core domain catalytic scaffold of the phosphatase branch of the HAD (haloalkanoic acid dehalogenase) enzyme superfamily, yet it has evolved to function as a mutas...

Three samples of carcinoembryonic antigens were purified from liver métastasesof primary colon cancer. The asparagine-linked sugar chains of carcinoembryonic antigens (CEA) were released as oligosaccharides by hydrazinolysis and the structures of oligosaccharides, thus obtained, was studied in combination with methylation analysis and several limited exoglycosidase digestions. All three CEAs c...

The effects of temperature on skin papillomas of newts (Cy nops pyrrhogaster) were studied. Newts bearing these tumors were maintained for 30 weeks at 4 ±1 (S.E.), 10 ±1,13 ±2, 25 ±1, and 30 ±1°.The diameters of the papillomas were measured externally. They decreased at 4, 25, and 30°, and increased at 10 and 13°.The effect of temperature on the tumor growth or regression began to appea...

Data defining the isolated effect of insulin on whole body protein and glucose metabolism in cancer patients are limited. Ten normal volun teers (controls), age 55 ±3 years (mean ±SEM); 8 cancer patients, age 61 ±3years, weight loss 2 ±1% (CANWL); and 8 cancer patients, age 55 ±2 years, weight loss 18 ±2% (CAWL), were studied in the postabsorptive state. Whole body leucine kinetics were d...

To elucidate the significance of tRNA modification for human lymphoid maturation and malignant transformation, the amount of tRNAs having guanosine in place of queuosine, i.e., (Q-)tRNA, was determined in several human lymphomas and leukemias by exchanging the respective unmodified guanosine residue for [3H]guanine, a reaction catalyzed by a specific tRNA transglycosylase from Escherichia coli....
